IMPROVEMENT IN THIMBLE-PINS FOR SUPPORTING POTTERY-WARE IN KILNS.

Specification forming part of Letters Patent No. 186,585, dated January23, 1877; application filed July 13, 1876.

-To all whom itmay concern:

- lowing is a full, clear, and exact description 'thereof, referencebeing bad to the accompanying drawings, and to the letters of referencemarked thereon, making a part of this specification. a

The nature of my invention'consists in the construction of a thimble-pinfor supporting crockery-ware in ovens or kilns while being burned, andalso in the construction of the die for making said pins, as will behereinafter more fully set forth. a

In order to enable others skilled in the art to which my inventionappertains to make and use the same,'I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure 1 is a section of the machine for making the thimble-pins. Fig. 2is a plan view of the lower or female die. Fig. 3 is a bottom view of.the upper or male die. Figs. 4 and 5 are perspective views of thethimble- Fig. 6 shows the application of my invention.

A represents the bed or base, provided with outward-projecting cars a aa at equal distances apart. In each of these projections is inserted athimble-pin, B, provided ,with a projecting pin, 0. This thimble-pin ismade of tapering angular form, having three sides, as shown in Fig. andthe arm (J projects from one corner thereof at the top. This arm isinclined slightly downward, rounded on top, and. at its end on top isformed a pointed spur, b. When the three thimble-pins thus constructedhave been inserted in the projections a of the base A, a-

saucer or other article, I), is placed on the arms 0 G, such articlebeing supported upon the points of the three spurs b, as shown in Fig.6. In each of the thimble-pins B is then inserted another similar pin,the arm of which extends above, but not in contact with, the saucer D.Another saucer is placed on the arms of such second set of pins, and soon, as

many as may be desired. The thimble-pins B B may be made four-sided andwedgeshaped, as shown in Fig. 5.

guide-pins, I I, having their lower ends screwed into a loose bar, J. Onthe under side of the bar J is the die K, for forming the arm (J of thethimble-pin. L is the mandrel that forms the inside of the thimble-pin,which mandrel passes through and is attached to. the fixed bar N, andthrough a corr'esponding opening in the loose bar J, so that said barcan move up and down on said mandrel.

As the upper part of the machine descends, the point of the mandrelenters the die G, and when the bar J and its die Kcome down in positionthe mandrel still continues to de-.

scend for a short distance. Then, at the upward stroke, the mandrelmoves a certain distance before the bar J commences to move.

Iam fully aware that thimble-pins having a round tapering exterior andopenings of corresponding shape are not new. In such case anydisturbance of thethimble-pins will turn them, and of course disturb theware supported by them.

By making the thinible-pins of angular tapering form, the sides fittingclosely together, they are prevented from being put out of place by anymovement of the ware.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

l. The angular tapering thimble-pin B, provided with the arm O,'having apointed. spur, b,- on its top at the outer end, substantially as and forthe purposes herein set forth.

2. The combination of the bed E, with die G and stop H, the fixed bar N,mandrel L, guide-pins I I, and bar J, with die K, all substantially asand for the purposes herein set forth. 1

In testimony that I claim the foregoing I have hereunto set my hand this24th day of 'June, 1876.

ELIAS LEAK.
